本文在长波假定下用流体力学线性稳定性理论对大动脉中血液流动求出了一种中性扰动。结果表明,心室或瓣膜等引起的扰动在一定条件下有可能是一种中性扰动,它可以沿着动脉管无变形地传播到动脉远端。这说明也许有可能提供一种通过在远离心脏的某些浅表动脉部位检测这种中性扰动,以了解心脏的某些功能的新方法。
In this paper, we use the theory of hydrodynamic linear stability to find a neutral perturbation to the blood flow in aorta under the assumption of longwave. The results show that the ventricular or valve-induced disturbances may be a neutral disturbance under certain conditions and can propagate along the arterial duct to the distal end of the artery without deformation. This suggests that it may be possible to provide a new way to understand some of the heart’s functions by detecting this neutral disturbance at some superficial artery distal to the heart.
